Abstract
 Two new unusual soyasaponins named 6''-O-methyldehydrosoyasaponin I (7) and desglucosylsoyasaponin A1 (10) along with eight known saponins, dehydrosoyasaponin IV (1), dehydrosoyasaponin III (= impatienoside A) (2), soyasaponin III (3), dehydrosoyasaponin II (= soyasaponin Bg) (4), soyasaponin II (5), dehydrosoyasaponin I (= soyasaponin Be) (6), soyasaponin I (8), and kudzusaponin SA3 (9), were isolated as their methyl esters and identified from the liquid culture of G. applanatum. Their structures were determined by chemical and spectroscopic analyses including 1D- and 2D-NMR as well as by comparison of their spectroscopic data with those of the reported in literatures. Although dehydrosoyasaponin IV was identified by LC-MS/MS method from soy protein isolate, this is the first report of the isolation of this compound. Dehydrosoyasaponin III (2) and kudzusaponin SA3 (9) were also isolated for the first time from soybean. The presence of soyasaponins in Ganoderma species seems to be unusual feature. Thus, we presumed that compounds 1-10 might all be derived from the defatted soybean flour which was added to the culture medium as a nitrogen source.
